When I SEARCH on Virtual/All result are empty or contain only messages from previously index mailboxes. I notice also that when SEARCH on Virtual/All directory "fts-flatcurve" is created but is empty:

Can you open a ticket at https://github.com/slusarz/dovecot-fts-flatcurve/issues?  FTS drivers don't require code to handle virtual mailboxes separately, but it is possible that this is hitting a code path in flatcurve that isn't touched with single mailbox queries so there could very well be a bug.
